ENSILAGE-OUTTING'rWHEEL MOUNTING.

naaaaeo.

Specification of Letters Patent.

Patented Aug. '3, w ll "to To (125 whom it may concern.

Be it known that I, From J. Bonnoon, a citizen of the United States, residing at Shortsville, in the county of Ontario and State of New York, have invented certain new an useful Improvements in Ensilage- Cutting-"Wheel Mountings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in ensilage cutting wheel mountings, the object being to provide novel means for mountingthe cutting wheel so as to prevent the binding twine used in binding fodder from becoming twisted around the cutting wheel shaft.

Another object of my invention is to provide a cutting wheel mounting which can be readily placed in position upon any of the well-known forms of ensilage cutter now in use, so as to protect the ends of the cutting knives, whereby the binding twine will be prevented from winding on the shaft to such an extent that the rotation of the cutting wheel is retarded thereby.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawing- Figure 1, is a side elevation of a portion of the cutting wheel provided with cuttinglmives showing the application of my improved construction of mounting thereto;

Fig.2 is a detail view partly in section showing the position of the knife 5 in respect to the guard lugs 11.

Fig. 8 is a detail view partly in section showing a slightly modified form of mounting, and

Fig. at is a similar view of still another modified form showing the collar formed integral with the hub of the cutting wheel. Like numerals of reference refer to like parts in the four figures of the drawing.

in the drawing, 1 indicates the body of the cutting wheel which is provided with a hub portion 2 fixed to the shaft 3 which is mounted in a bearing a in the ordinary manner. The cutting wheel is provided with tangentially arranged cutting knives 5 carried by supports 6 which are placed at equal distances on the face of the wheel, these lmives being preferably provided with pointed portions My improved invention consists in securing on the cutting, wheel-carrying shaft 3, a collar 8 which is'fixed thereto by a set screw 9 so as to rotate therewith and is provided with a flange portion 10 extending over the reduced portion of the bearing 4 said flange portion having tapering guard lugs 11 extending over the points 7 of the knives 5 as clearly shown in Fig. 1, so as to protect these points and as the binding twine around the bundles of fodder is fed into the ensilage cutter, it is prevented from winding on the shaft as the collars 8 move with the cutting wheel and as the points are pro tected by the guard lugs 11, the twine passes through the machine without winding around the bearing as now very often happens in ensilage cutters of this character.

In the modification shown in Fig. 3, l secure a collar 8 on the hub 52 of the cutting wheel 1 by set screws '9' so as to rotate therewith, said collar being provided with a flange portion extending over the reduced portion of the bearing 4 and is provided with an annular inwardly projecting flange 10 as clearly shown. The collar 8' is provided with a guard lug 11 for the point '2' of the knife and it will be seen by this construction that I provide a cutting wheel mounting in which the collar is carried by the hub of the cutting wheel and emends over a reduced portion of the the shaft so as to protect the same.

In the modification shown in Fig. 4, I provide the hub 2 with an extension forming a collar 8 which is provided with a flange portion 10 extending over the re duced portion of the bearing d, said flange having guard lugs 11 to receive the points 7 of the knives.

It will be seen that l have provided means for mounting the cutting wheel in such a manner that the binding twine and the stringy material being cut is prevented from being wound upon the shaft carrying the cutting wheel as a collar is provided which extends over the shaft bearing having guard lugs for preventing the ends of the knives from catching the binding twine beyond the inner end of the shearing plate.

From the foregoing description, it will be seen that l have provided an ensilage cutting wheel mounting in which the cutting wheel shaft is provided with a collar having a flange protecting the bearing of the ill bearing of ion lid

shaft and provided with guard lugs extending over the point of the knives carried by the cutting wheel in such a manner that the points are protected so that the binding twine and material being cut is carried to the cutting edge of the knife and cut instead of being wound upon the shaft.

I claim:

1. In an ensilage cutter, the combination with a bearing, of a shaft mounted in said bearing carrying a cutting wheel, cutting knives carried by said wheel, a collar fixed to said shaft extending over said bearing, and lugs carried by said collar extending over the points of said knives.

2. The combination with a bearing having a reduced portion, of a shaft mounted in said bearing, a cutter wheel fixed to said shaft, knives carried by said cutter wheel, a collar fixed on said shaft having a flange portion extending over the reduced portion of said bearing forming a guard therefor, and guard lugs carried by the flange of said collar extending over the points of said knives.

3. An ensilage cutting wheel mounting, comprising a bearing having a reduced portion, a shaft mounted in said bearing, carrying a cutting wheel, cutting knives carried by said cutting wheel, a collar fixed to said shaft and rotating therewith, said collar having a flange extending over the reduced portion of said bearing and tapering guard lugs having inclined faces extending outwardly from the flange of said collar over the points of said knives.

4. The combination with a rotary cutting wheel of a collar mounted to rotate therewith, and lugs carried by said collar extending over the knives of said wheel.

5. In an ensilage cutter, the combination with a rotating shaft, of a cutting wheel carried by said shaft provided with knives, a collar mounted to rotate with said cutting wheel, and guard lugs having inclined faces carried by said collar extending over the points of said knives.

6. In an ensilage cutter, the combination with a bearing, of a shaft mounted in said bearing, a cutting wheel carried by said shaft provided with cutting knives, a collar mounted to rotate with said cutting wheel having a portion extending over said bearing, and guard lugs having inclined faces carried by the collar extending over the points of said knives.

In testimony whereof I hereunto atlix my signature in the presence of two witnesses. FRED J. BULLOCK. lVitnesses:
